Abstract

Compounds of the formula (II) in which A, B, G, W, X, Y and Z may have the meanings given in the description are highly suitable for controlling animal pests such as insects and/or spider mites by treating the soil/growth substrate by watering or droplet application or dip application. In soil applications, the activity of crop protection compositions comprising active compounds of the formula (II) can be improved by adjuvants. The present invention describes corresponding processes and suitable compositions.

Description

The present invention relates to the use of tetronic acid derivatives for controlling insects and/or spider mites by watering, droplet application or dip (immersion) application.

It is known that certain substituted Δ³-dihydrofuran-2-one derivatives have herbicidal properties (cf. DE-A-4 014 420). The synthesis of the tetronic acid derivatives (such as, for example, 3-(2-methylphenyl)-4-hydroxy-5-(4-fluorophenyl)-Δ³-dihydrofuran-2-one) which are used as starting compounds, has also been described in DE-A-4 014 420. Compounds of a similar structure are known from the publication Campbell et al., J. Chem. Soc., Perkin Trans. 1, 1985, (8) 1567-76 without any insecticidal and/or acaricidal activity being mentioned. 3-Aryl-Δ³-dihydrofuranone derivatives having herbicidal, acaricidal and insecticidal properties are furthermore known from EP-A-528 156, EP-A-0 647 637, WO 95/26 345, WO 96/20 196, WO 96/25 395, WO 96/35 664, WO 97/01 535, WO 97/02 243, WO 97/36 868, WO 98/05638, WO 98/25928, WO 99/16748, WO 99/43649, WO 99/48869, WO 99/55673, WO 00/42850, WO 01/17972, WO 01/23354, WO 01/74770, WO 03/013 249, WO 04/024 688, WO 04/080 962, WO 04/111 042, WO 05/092897, WO 06/000355, WO 06/029799, WO 06/089633, WO 07/048,545 and WO 07/073,856.

Surprisingly, it has now been found that the tetronic acid derivatives are also highly suitable for controlling insects and spider mites by watering on the ground (known as “drenching” by persons skilled in the art), droplet application on the ground (known as “drip application” by persons skilled in the art) or dip application.

Accordingly, the present invention relates to the use of tetronic acid derivatives for controlling insects and/or spider mites by drenching, in irrigation systems as drip application or by dip application. The present invention relates in particular to these application forms on artificial soilless cultivation substrates (for example rock wool, glass wool, quartz sand, gravel, expanded clay, vermiculite), outdoors or in closed systems (for example greenhouses or under cloches) and in annual (for example vegetables, spices, ornamental plants), but also perennial (for example citrus plants, conifers, ornamental plants, shrubs) crops.

The present invention furthermore relates to the improvement of the action of agrochemical compositions in soil applications, to the agrochemical compositions suitable for this application and to their use for controlling harmful insects and/or spider mites.

Agrochemically active compounds can be applied by various means for controlling harmful organisms. In addition to foliar treatment, it is also possible to treat the cultivation substrate. This may be soil, and also specific substrates based inter alia on peat mosses, coconut fibers, rock wool, such as, for example Grodan®, pumice, expanded clay, such as, for example, Lecaton® or Lecadan®, clay granules, such as, for example, Seramis®, expanded plastic, such as, for example, Baystrat®), vermiculite, perlite, artificial soil, such as, for example, Hygromull®, or combinations of these substrates. Hereinbelow, all these cultivation substrates are referred to as soil. Application of active compounds into or onto the soil both brings harmful organisms living in the soil into contact with the active compound and initiates the uptake of systemically active compounds by the roots. Various auxiliaries for improving the action of agrochemically active compounds in foliar treatment are already known. These include, for example, penetrants which facilitate the penetration of the active compounds into the plant (for example WO 03/000053). Corresponding adjuvants for soil applications of insecticides and fungicides have not yet been described. The effect of soil penetration aids, which accelerate the penetration of irrigation water into dry soils (for example Agri-Prep® CS from Northwest Agricultural Products), are known.

It is also known that the surfactants can have an effect on the distribution of permethrin in the soil (Howell, McMullan P. M. (ed.), 1998, Adjuvants for Agrochemicals, Proceedings of the 5th international Symposium on Adjuvants for Agrochemicals, Memphis, USA, pp. 247-253).

The improvement of herbicidal compositions by optimized formulations has also been described (Chung et al., Pesticide Science, 1993, 38 (2-3), pp. 250-252).

Surprisingly, it has now been found that the biological activity of insecticidal and/or acaricidal compositions in soil applications can be improved by adding an adjuvant to these compositions. Here, the adjuvant can either be a component of the concentrated formulation (in-can formulation) or be added during the preparation of the ready-to-use pesticide solution (tank-mix application). The improved activity manifests itself in particular in the control of foliar pests which are controlled by a systemic action of the active compounds. In this manner, the compositions according to the invention allow the active compound application rate to be reduced or improved action to be achieved at the same application rate. In addition, the consumption of water can be minimized.

Accordingly, the present invention also provides the use of adjuvants for improving the activity of agrochemical compositions in soil applications, for example by spraying onto the soil, watering, side-dressing, shower-drenching, overhead-drenching, dip application or application in connection with an irrigation system (drip irrigation).

We have now found novel suspension concentrates for this use, comprising

• • at least one agrochemically active compound, solid at room temperature, from the group of the insecticides and/or acaricides of the formula (II),
  • at least one adjuvant,

In addition to concentrated formulations, the invention also provides dilute ready-to-use compositions. The invention furthermore provides the use of these compositions for controlling foliar pests.

• (I-2) compositions comprising dioctyl sodium sulfosuccinate and sodium benzoate, commercially available, for example, in the product series Aerosol®; the dioctyl sodium sulfosuccinate:sodium benzoate weight ratio is preferably from 5:1 to 6:1,
• (I-3) terminally capped alkoxylated fatty alcohols and terminally capped alkoxylated straight-chain alcohols, commercially available, for example, in the product series Plurafac®; preference is given to ethoxylated and/or butoxylated fatty alcohols and terminally capped ethoxylated and/or butoxylated straight-chain alcohols,
• (I-4) tributylphenol polyglycol ethers having 10 to 15 EO units (where EO is ethylene oxide), commercially available, for example, in the product series Sapogenat®,
• (I-5) polyalkylene oxide-modified polymethylsiloxanes, commercially available, for example, in the product series Silwet®,
• (I-6) branched alkanol alkoxylates of the formula CH₃—(CH₂)_t—CH₂—O—(—CH₂—CH₂—O—)_u—H, in which t represents numbers from 9 to 10.5 and u represents numbers from 6 to 25 (preferably from 8 to 12) and t and u are average values, commercially available, for example, in the product series Lutensol®,
• (I-7) betaine
• (I-8) polyalkoxylated triglycerides, where the triglyceride is preferably of vegetable origin, commercially available, for example, in the product series Crovol®,
• (I-9) alkoxylated fatty amines, commercially available, for example, in the product series Armoblen®,
• (I-10) sodium laureth sulfate, commercially available, for example, in the product series Genapol®,
• (I-11) PEG-10 coconut alcohol, commercially available, for example, in the product series Genapol®,
• (I-12) compositions comprising corn syrup, petroleum oil and nonionic emulsifier, commercially available, for example, in the product series Superb®.

The advantageous effect of these adjuvants is given in principle for the insecticides and/or acaricides from the classes of the tetronic acid derivatives.

Insecticidal compositions according to the invention may, in addition to at least one of the active compounds mentioned above, also comprise other active compounds, such as further systemic insecticides, attractants, sterilants, bactericides, systemic acaricides, nematicides, fungicides, growth-regulating substances, herbicides, safeners, fertilizers or semiochemicals.

The compositions according to the invention may furthermore comprise synergists. Synergistic agents are compounds which increase the action of the active compounds, without it being necessary for the synergistic agent added to be active itself.

The compositions according to the invention may furthermore comprise inhibitors which reduce degradation of the active compound after application.

The compounds are employed in a customary manner appropriate for the formulation. The treatment according to the invention of the plants and plant parts with the compositions takes place by soil treatment, for example in the form of one of the variants mentioned at the outset.

As already mentioned above, it is possible to treat all plants according to the invention. In a preferred embodiment, wild plant species and plant cultivars, or those obtained by conventional biological breeding, such as crossing or protoplast fusion, and parts thereof, are treated. In a further preferred embodiment, transgenic plants and plant cultivars obtained by genetic engineering, if appropriate in combination with conventional methods (Genetically Modified Organisms), are treated.

Particularly preferably, plants of the plant cultivars which are in each case commercially available or in use are treated according to the invention. Plant cultivars are to be understood as meaning plants having new properties (“traits”) and which have been obtained by conventional breeding, by mutagenesis or by recombinant DNA techniques. They can be cultivars, bio- or genotypes.

Depending on the plant species or plant cultivars, their location and growth conditions (soils, climate, vegetation period, diet), the treatment according to the invention may also result in superadditive (“synergistic”) effects. Thus possible are, for example, reduced application rates and/or a widening of the activity spectrum and/or an increase of the activity of the compositions according to the invention, better plant growth, increased tolerance to high or low temperatures, increased tolerance to drought or to water or soil salt content, increased flowering, easier harvesting, accelerated maturation, higher harvest yields, higher quality and/or higher nutrient value of the harvested products, increased storability and/or processibility of the harvested products, which exceed the effects normally to be expected.

The transgenic plants or plant cultivars (i.e. those obtained by genetical engineering) which are preferably treated according to the invention include all plants which, in the genetic modification, received genetic material which imparted particularly advantageous useful properties (“traits”) to these plants. Examples of such properties are better plant growth, increased tolerance to high or low temperatures, increased tolerance to drought or to water or soil salt content, increased flowering performance, easier harvesting, accelerated maturation, higher harvest yields, better quality and/or a higher nutritional value of the harvested products, better storability and/or processability of the harvested products. Further and particularly emphasized examples of such properties are a better defence of the plants against animal and microbial pests, such as against insects, mites, phytopathogenic fungi, bacteria and/or viruses, and also increased tolerance of the plants to certain herbicidally active compounds. Examples of transgenic plants which may be mentioned are the important crop plants, such as cereals (wheat, rice), corn, soybeans, potatoes, sugar beet, tomatoes, peas and other types of vegetable, cotton, tobacco, oilseed rape and also fruit plants (with the fruits apples, pears, citrus fruits and grapes), in particular emphasis is given to corn, soybeans, potatoes, cotton, tobacco and oilseed rape. Traits that are emphasized are in particular increased defence of the plants against insects, arachnids, nematodes and slugs and snails by toxins formed in the plants, in particular those formed in the plants by the genetic material from Bacillus thuringiensis (for example by the genes CryIA(a), CryIA(b), CryIA(c), CryIIA, CryIIIA, CrylIIB2, Cry9c Cry2Ab, Cry3Bb and CryIF and also combinations thereof) (hereinbelow referred to as “Bt plants”). Traits that are also particularly emphasized are the increased defence of the plants against fungi, bacteria and viruses by systemic acquired resistance (SAR), systemin, phytoalexins, elicitors and resistance genes and correspondingly expressed proteins and toxins. Traits that are furthermore particularly emphasized are the increased tolerance of the plants to certain herbicidally active compounds, for example imidazolinones, sulfonylureas, glyphosate or phosphinotricin (for example the “PAT” gene). The genes which impart the desired traits in question can also be present in combination with one another in the transgenic plants. Examples of “Bt plants” which may be mentioned are corn varieties, cotton varieties, soybean varieties and potato varieties which are sold under the trade names YIELD GARD® (for example corn, cotton, soybeans), KnockOut® (for example corn), StarLink® (for example corn), Bollgard® (cotton), Nucotn® (cotton) and NewLeaf® (potato). Examples of herbicide-tolerant plants which may be mentioned are corn varieties, cotton varieties and soybean varieties which are sold under the trade names Roundup Ready® (tolerance against glyphosate, for example corn, cotton, soybeans), Liberty Link® (tolerance against phosphinotricin, for example oilseed rape), IMI® (tolerance against imidazolinones) and STS® (tolerance against sulfonylurea, for example corn). Herbicide-resistant plants (plants bred in a conventional manner for herbicide tolerance) which may be mentioned include the varieties sold under the name Clearfield® (for example corn). Of course, these statements also apply to plant cultivars having these genetic traits or genetic traits still to be developed, which plants will be developed and/or marketed in the future.

The plants listed can be treated according to the invention in a particularly advantageous manner with the compositions according to the invention. The preferred ranges stated above also apply to the treatment of these plants. Particular emphasis is given to the treatment of plants with the compositions specifically mentioned in the present text.

The compositions are also suitable for controlling animal pests in the domestic field, in hygiene and in the protection of stored products, in particular insects, arachnids and mites, which are found in enclosed spaces such as, for example, dwellings, factory halls, offices, vehicle cabins and the like. They can be employed alone or in combination with other active compounds and auxiliaries in domestic insecticide products for controlling these pests. They are active against sensitive and resistant species and against all developmental stages. These pests include:
